To all whom it may conce.'

Be it known that I, Romana; L. MUNsoN, a citizen of the United States, and a resident of Detroit, in the county of Wayne and `State of Michigan, have invented an llmprovement in Collapsible Wheel-Flanges, of which the following is a specification.

My invention is an improvement in collapsible wheellanges, and has for its object to provide a device of the character specified, intended for attachment to whee s of motor or other vehicles, wherein the flange is sectional, and is supported on the wheel in such manner that it may bel collapsed within the periphery of the wheel, when the .wheel is on the road, and which may be expanded beyond the periphery to permit the wheel to be used upon rails.

ln the drawings:

Figure 1 is a side view of a wheel provided with the improved flange, with the flange expanded.

Fig. 2 is an edge view of the wheel.

Fig. 3 is a side view with the flangecontracted. A

Fig. 4 is an edge rview of the same.

Figs. 5 and 6 are sections on the line 5-5 and 6 6, respectively, of Fig. 1, Fig. 5 looking in the direction of the arrows adjar cent to the line.

In the present embodiment of the invention the wheel 1, which may be of any usual or desired construction, has secured thereto Specification of Letters Patent.

, rotate on the frame,

a disk or annular frame 2, by means of boltsand nuts 3, the'bolts being passed throu hregistering openings in the frame and in t e rim of the wheel, with the frame on the inner side of the wheel, and the frame is of such diameter that the peripheralV ed e thereof will be at the metal rlm 4 of t e wheel.

The 'Hange consists of four. similar sections 5,each of which is a quadrant, and one end of each flange section has integral. therewith a curved arm 6, and the said arm is pivoted to the frame 2 as indicated at Z.

These arms 6 curve in the same direction and are similarly placed, each having its` convex -edgeltoward the flange section. The ends of the flange sections are beveled as shown at 5a, to permit them to lap upon each and theinner end of each link is pivotally connected to a ring 9,'which is mounted to l being arranged coaxial wlth. the wheel. This ring as shown more particularly in Fig. 5 has an annular peripheral groove 10 for edge ofthe frame 2, and the ring is thus rotatably connected with the frame. The ring 1s provided with an opening which is adapted to register with the openlngs in the frame .2, when the Hangs is in expanded or contracted position, and these openings are adapted to receive a bolt 11, which is engaged by a nut 12,. to fix the ring' with respect to the frame, and to hold the flange expanded or contracted. It will be obvious that when the ring is rotated with respect to the frame, the ilange sections will be moved outwardly or inwardly, swinging on the curved arms 6. When the ring is rotated in the direction of the uppermost arliatented tpr. 3, 121'?. Application nled November 23, 1916. Serial No. 133,043.

receiving the inner row in Fig. 3, the links will be pushed outf ward, and will push out the flange sections, which will swing on the curved arms 6, and will eventually attain the position shown in Fig. 1. Atthis point the link 8 of each section laps over the curved arm of the succeeding section, and each link engages beneath a locking lug 13 which is .secured to the frame at this point. The locking lug holds the link firmly against the curved arm, and the link holds the curved arm firmly against the frame, so that each Hange section is locked at both ends.

ln use, when the wheel is on an ordinary road, the flange sections occupy the posi- A tions shown in Figs. 3 and 4r, bein contracted within the periphery of the tire 14. They are held in this position by means of the bolt 12, and when .it is desired to run the vehicle on rails, for instance, the bolt 12 is removed, the ring 9 is oscillated, to move the sections 5 outwardly into the position in Fig. 1, and when they are in proper position another opening in the frame 2 will register with the opening in the ring 9 and the bolt 12. is inserted into these reglsterin openings to lock the parts in the expande condition.
